The doctor at the day hospital I attend has suggested adding a small dose of Lithium (200mg) to help boost the antidepressant I'm taking which is sertraline 200mg which is max dose.

I'm also on Pregabalin 150mg 3 x a day for neuropathic pain and anxiety and Promethazine 25 mg once or twice a day as needed to calm me.

Has anyone else been on a low dose of Lithium for depression? I am concerned about being on so many pills and what the side effects might be? the dr said its a low dose so shouldn't get many side effects but I've read about weight gain and hair loss and needing blood tests etc.

Any advice?
